Data Grid (Pulling my hair out!)

I am using Data Grid and it was working fine. I don't think I made any changes but now it doesn't retrieve the table, and in the program when I acess DataEnvironment1 I get an error indicating that DataEnvironment1 is not open. I have another form with a Data Grid with similiar properties and I can acess DataEnvironment1 without opening it. I don't know why it wont populate the grid but I think it might be something with the DataEnvironment1.....PLEASE HELP I have wasted 3 hours just trying to get this to work when it was already working right!

there are many properties that need to be set properly
further if the DBGrid is bound to a Data Control then there are many more properites on the Data Control that could be wrong

You would have to furnish all these settings in a post for anyone to be able to help you
